Mugger Crocodile

Crocodylus palustris

Also known as Marsh Crocodile, Broad-snouted Crocodile, Mugger

Mugger crocodiles are broad-snouted freshwater reptiles that spend cool mornings basking on river sandbanks before retreating into self-dug underground burrows during temperature extremes. Highly social compared to many other crocodilians, they often congregate peaceably around perennial waterholes and have even been observed balancing twigs on their snouts to lure nest-building water birds. Both parents actively defend their nest and guard the newly emerged hatchlings for up to a full year.

Why interaction risk is high
A large predatory reptile capable of delivering fatal bites; maintain a safe distance and stay out of the water.
Why it is dangerous
Possesses immense jaw strength and powerful teeth capable of crushing bone and inflicting fatal crushing injuries or drowning victims.
How to recognize a risky encounter
Recognizable by an exceptionally broad snout, heavily armored keeled scales, and an olive-tan to dark grey hide.
What to do
Never approach, feed, or harass; stay well back from vegetated water edges where ambush strikes occur.
What to notice
Look for broad snouts and robust bodies basking along sandbars in protected reserves across South Asia.
Support conservation
Report sightings to local wildlife authorities in conflict zones and refrain from disturbing active nest burrows.
Responsible observation
  • Distance: Maintain at least 30 meters from shorelines where crocodiles bask or hunt.
  • Water Safety: Avoid swimming, wading, or washing near water bodies known to harbor crocodiles.
  • Basking Etiquette: Use binoculars from an elevated bank or vehicle to prevent startling the reptile into defensive dives.
